[Abstract]:As the key link of smart grid construction and the link of power transmission, transmission line is an important part of power system. Once the operation failure occurs, it will lead to the collapse of regional power system, resulting in serious power network accidents. In order to ensure the safety, reliability and stability of transmission lines, the construction of on-line monitoring of transmission lines is very important to avoid power network accidents and ensure the safety of transmission lines. According to the typical engineering application experience of on-line monitoring of transmission network in China, this paper probes into the relevant technology support of smart grid, and studies the key technology of long-distance on-line monitoring of transmission line. In order to monitor the real-time transmission line body and surrounding conditions. This paper mainly includes the type selection design of monitoring device, the power supply design of front end monitoring device and main station, the transmission and communication design of monitoring data, and the field survey of key hidden trouble lines and the application design of related on-line monitoring device. Finally, the concrete application effect after the system pilot construction is analyzed in detail. Through accessing the system, a large number of actual operation data of transmission line are accumulated, and the safety management level and operation level of transmission line are improved significantly. The hidden trouble of high voltage key lines is controllable, controllable and in control, which provides an important practical basis for the development of smart grid and the continuous deepening of on-line monitoring.
